You have trembling grass growing in the garden and you want more? Then simply increase it. There are two ways to do this.

Not every quaking grass (Briza) is perennial and therefore suitable for reproduction. However, the propagation of Briza media tremor grass, which is common in Germany, is easy and uncomplicated. In this way, new specimens can be grown from existing plants, which you can then use for group plantings. Or you can simply surprise friends and relatives with this pretty ornamental grass, which will surely find a place in their garden.

You can basically multiply quaking grass by dividing and seeds. We would like to explain both variants to you in more detail below.

Multiplication by division

When propagating by division, the root of an existing plant is halved or, depending on its size, also divided into several segments. Quaking grasses do not form roots that reach far into the ground, but rather branched rhizomes that are only a few centimeters below the surface of the earth. So it will be very easy to dig out the existing plant and multiply in this way.

A root division usually gets the tremor very well, because division here also means rejuvenation. The plants then grow better and appear vigorous and healthy.

When is the best time?

Root division should be done in spring. The floor should then already be frost-free. So the divided plants can develop well separately from each other and develop an independent and strong root system.

Planting instructions

  1. Carefully dig out the existing plant.
  2. Remove soil from the root ball.
  3. Rinse the rhizomes well so that there is no germ transfer.
  4. Share rhizomes. There should be at least two nodes on each segment.
  5. Place rhizomes on newspaper.
  6. Let the interfaces dry for a few hours in the sun.
  7. Plant plants separately.

Important:
The division should be carried out with a sharp and aseptic knife. You can also use a spade. By the way, garden tools keep you germ-free by cleaning them with alcohol.

Propagate by sowing

The propagation by seeds will probably also promise success to inexperienced hobby gardeners, because the seeds of the tremor grass are very good at germinating. With quaking grass, it is assumed that the germination rate is hardly less than 100 percent.

When is the right time?

You can start sowing in early spring. Then it can be assumed that by mid-May you will have healthy and strong young plants that can be transplanted into beds or tubs.

Planting instructions

  1. Fill the growing soil in pots or plant trays.
  2. Spread seeds on the substrate.
  3. Cover seeds only slightly with soil.
  4. Make seeds bright and warm.
  5. Ensure a constant, light moisture.
  6. Apply plastic or glass cover for accelerated germination.

Tip:
The substrate should not contain too many nutrients. A mix of sand and peat appears ideal. You can add Perlite to this. You can mix about a quarter of pearlite rock in the planter. Perlite, as a natural product, supports water and heat storage and thereby increases the already very good germination rate, so that you hardly suffer any losses.

When can germination be expected?

If you keep the seeds evenly moist and the temperature is at least 20 degrees, germination will start after about ten days. All germinable seeds should then have risen within two weeks.

What happens to the young plants?

Germination begins very quickly and soon it will be tight in the planter. The strongest plants now get their own plant pot. The bright and warm location is maintained. The young plants also receive watering regularly. If the young plants have developed sufficiently, you can plant them outdoors from mid-May.

What to think about direct sowing of tremor seeds?

In general, there is nothing wrong with planting the seeds directly outdoors. This can happen from the end of March. However, frost should no longer prevail. Germination is less reliable with direct sowing. There are numerous factors that underpin this:

  • Floor too wet
  • Occurrence of night frost
  • Appearance of pests
  • no constant temperatures

So this method is not advisable. The propagation by division and sowing in plant pots is then more promising.
